Cleaning the black water tank

I have an 06 Holiday Rambler Admiral. I have owned it for 3 years and the black water tank has never drained completely.

Out side, where you dump the tank, there is a hook up for a hose that is supposed to flush the tank. When I hook up the hose and turn the water on nothing happens. I have the tank drain open and no water comes out.

The tank gauge always reads 1/2 full and there always seems to be something in the tank when you look in it.

I tried putting in 20 pounds of ice on my last trip. I read that it would slosh around and free up anything that was caught in there. It seems to have made no difference.

Anyone out here have any ideas?
